資訊交換緣起

位元世界 1/2

一個位元 (bit) 可以代表一個事實的兩個狀態，例如，電燈的“開”或“關”、性別的”男”或”女”（只有這樣子嗎？）。

兩個位元可四種狀態，有下列組合： 00 、 01 、 10 、 11 。方向，00 代表往前、 01 代表往後， 10 代表往右， 11 代表往左。

資訊的層級事實 fact

– 所關心的某一事件。描述方向、性別。資料 data

– 此事件可以攜帶的資料。 00 代表往前、 01 代表往後， 10 代表往右， 11 代表往左。

資訊 information– 資料經過有目的處理。某人從原點 (0,0) 出發，收集 {00, 00, 10,

00} 資料，得知離開原點至座標 (1,3)知識 knowledge

– 學習所得，前往該點有哪些路徑。 {00,10,00,00} 也可到座標 (1,3) 。資訊重現。

智慧 wisdom– 可以產生新的路徑

HL7 總會介紹

http://www.hl7.org/http://www.hl7.org/

What’s HL7

Health Level Seven is one of several American National Standards Institute (ANSI) -accredited Standards Developing Organizations (SDOs) operating in the healthcare arena.

Members of Health Level Seven are known collectively as the Working Group, which is organized into technical committees and special interest groups.

– The technical committees are directly responsible for the content of the Standards.

– Special interest groups serve as a test bed for exploring new areas that may need coverage in HL7’s published standards.

HL7's Mission

HL7 is an international community of healthcare subject matter experts and information scientists collaborating to create create standardsstandards for the exchange exchange, managementmanagement and integrationintegration of electronicelectronic healthcare information.

HL7 promotes the use of such standards within and among healthcare organizations to increase the effectiveness and efficiency of healthcare delivery for the benefit of all.

What Does the Name HL7 Mean

"Level Seven" refers to the highest level of the International Organization for Standardization (ISOISO) communications model for Open Systems Interconnection (OSIOSI) - the application level) - the application level.

The application level addresses definition definition of the data to be exchanged, the timing of the interchange, and the communication of certain errors to the application.

The seventh level supportssupports such functions as security checks, participant identification, availability checks, exchange mechanism negotiations and, most importantly, data exchange structuring.

2007 HL7 Publishing Calendar

Ballots

The end product of a ballot process is a document. The document could stand on its own. However,

most balloted documents are a part of a published Standards Document (e.g., HL7 2.6, HL7 3.0, etc.)

Ballots

Documents can be:– ReferenceReference ： Content is harmonized during HL7 meetings or appr

oved by the HL7 Board. It is not subject to ballot acceptance.– InformativeInformative ： Content is balloted by the general membership. Ho

wever, it is not considered to be a structural part of the Standard but only supporting information.

– NormativeNormative ： Content is balloted by the general membership and is considered a structural component of the HL7 Standard. Negative ballots must be resolved.

– Draft Standards for Trial UseDraft Standards for Trial Use (DSTU) ： Content is balloted by the general membership as the draft of a future standard which will, following a pre-specified period of evaluation and comment (usually 2 years), be expeditiously incorporated into normative standard.
